fwptt it's a Web application tester program for load testing web applications. It can record normal and ajax requests. I tested it on asp.net applications, but it should work with jsp, php or other.
fwptt let's the user import the recoded browsing sessions made with Fiddler.
These http requests can be imported and used to generate
a c# class that will call all the http request that the user has previously recorded.
Than using the tests runner the user will be able to run the code from his c# testing class.
You can record your browsing actions using any browser you like IE, Firefox Opera etc.
Also becaues the actual test is a C# class you can modify it. The class has functions for handling the query/post params
which you can use to easily add more or delete some of the existing ones and of course you'll have at your disposal all the .net classes
so you can connect to a database open a file etc.
